The Greatest American Hero

Reseda Rose - S1-E6

Revealing mistake: During the meeting on the beach, while Bill remains on the hill Ralph flies to the surfaced submarine, and in Ralph's closeups on the sub the crinkled black set wall behind him is painfully obvious.

Don't Mess Around With Jim - S2-E3

Revealing mistake: While they're on Beck's jet Ralph uses the suit's telekinetic powers on the ice-filled cup, and Ralph tells Bill he'll do it again with a magazine, then when it cuts to the first closeup of the magazines the stunt wire attached to the book is visible. (00:15:45)

Classical Gas - S2-E5

Revealing mistake: When Ralph blocks Hydra's rocket from its target, in the closeup as the rocket hits Ralph's abdomen the thin stunt wire is visible at the rocket tail. Then while Bill is fighting with Hydra, when Ralph is in mid-air heading to Bill the stunt apparatus is visible at Ralph's waist. (00:40:00)

Plague - S2-E8

Revealing mistake: At the paramilitary base, after Bill tells Bunker he has "a real cute bivouac goin'," it cuts to a shot of Ralph searching for Bill's location, and the stunt apparatus is visible at Ralph's waist area. (00:21:30)

Super Grover

Plague - S2-E8

Revealing mistake: When Bill is pushed out of the helicopter and Ralph rescues him in mid-air, its obvious in some shots that it is two sky-divers dressed as Ralph and Bill. Firstly you can see the parachute back-pack bulges on both men. Also the wind is blowing up on Ralph even though he isn't meant to be descending.

Train of Thought - S2-E9

Revealing mistake: When Ralph stops the hijacked train before it reaches the city of Bakersfield, due to the close proximity of the camera it's too obvious that Ralph's footwear has been altered for the stunt, as he glides across the tracks. (00:44:30)

Super Grover

The Shock Will Kill You - S2-E13

Revealing mistake: While Ralph, Pam, and Bill are at the motel, Ralph wraps up all the metal plate covers and cutlery inside the bedspread, then when Ralph walks back and forth we can see the wires attached to the bedspread bundle as it moves. (00:18:15)

Super Grover

Heaven is in Your Genes - S3-E6

Revealing mistake: While Ralph is in mid-air, en route to the airport cafe, something dips into view at the top left corner of the screen. Then when Ralph takes off from that cafe, two shots later as he's in mid-air, we can see the shadow of the helicopter filming the background stock footage, but it's been flipped so the helicopter is flying backwards, and when more background footage is shown again the helicopter shadow is flying properly. (00:13:15)

Super Grover

Desperado - S3-E12

Revealing mistake: When Ralph picks up the guy who was stealing mustangs and takes off with him over his shoulder, while they're in the air the cushion under Ralph is visible in the closeups. (00:18:00)

Super Grover

Dreams - S2-E17

Audio problem: After Ralph gets the holograph showing Pam and Bill taken hostage, when Ralph makes an embarrassing entrance into the youth crime seminar he quickly impersonates a singing telegram, and his mouth is out of sync as we hear the phone number. (00:37:30)
